使用sprintf的这个Perl代码的C++等价物是什么？

Question

我需要模仿以下Perl代码的功能

if($file =~ /^([^_]+)_([^_]+)_MA_(\d{4})(\d\d)(\d\d)_(\d\d)(\d\d)(\d\d)\.MA$/) {
  my ($radar, $beam, $year, $month, $day, $hour, $min, $sec) =
      ($1, $2, $3, $4, $5, $6, $7, $8);
  my $file_ts = sprintf("%04d-%02d-%02d %02d:%02d:%02d",
      $year, $month, $day, $hour, $min, $sec);

  # ...
}

在C++中.我使用哪种功能？

好吧,总有选择使用sprintf:

或者你可以使用stringstream,作为更多的C++ - 替代品.
